Fisher 5867352 Control Valve Stem

Technical Specifications

Model：5867352 Brand：Fisher Product Type: Control valve alloy valve stem

Module Feature

Fisher 5867352 is precision machined alloy valve stem for Fisher globe control valve. It connects actuator to valve plug and converts actuator linear thrust into plug stroke movement. The material has excellent tensile strength,wear resistance and corrosion resistance. Widely used in oil,gas,chemical and power plant globe control valves.

Working principle: Transfer actuator thrust to valve plug for flow regulation Onboard components: Alloy stem body, thread section, locating shoulder

Environmental

Operating temperature:-40℃ ~ +425℃ Ambient humidity:5~95% non-condensing Certification:CE Status:Fisher valve trim spare part

System compatibility

Compatible with matched Fisher globe control valve trim assembly and pneumatic diaphragm actuator for industrial process control system.

Function

5867352 is valve stem manufactured by Fisher. It transmits linear force from actuator pushrod to valve plug to realize opening,closing and modulating of control valve. The straightness and surface finish directly affect packing sealing performance and valve stroke smoothness. Scratches or bending will cause packing leakage and valve sticking. It is essential spare part for valve trim maintenance.

Installation

Follow lockout/tagout safety procedure before installation. Isolate pipeline and release process pressure. Disassemble valve bonnet and old stem. Install new valve stem, align thread connection with valve plug and actuator pushrod. Check stem straightness and sliding clearance. Reassemble valve and perform hydrostatic test and packing leakage inspection.

Interface

Thread connection with valve plug and actuator pushrod, sliding fit through packing box, no LED indicators on 5867352.

Diagnostic

External packing leakage: Stem surface scratch or corrosion. Valve sticking: Stem bending or surface deformation. Unstable stroke: Thread wear or loose connection between stem and plug.
